5 Application Circuit

6 Module dimension drawing 1. The back plate of the IC should connect to GND. 2. When using cylinder crystal, please take special care as below: (1) Please don t apply solder to the body directly, as it may cause characteristic deterioration. (2) Please fix the unit firmly with elastic glue on the board. (3) Please don t cut or bend the leads within 0.5 mm from the base of the cylinder body. (4) Please don t use ultrasonic washing and ultrasonic welding on the unit, because it may be damaged. (5) Please ask how to use it to avoid damage for detail from your crystal supplier.
